WEIGHING-SCALE.

Specification of Letters Patent No. 22,810, dated February 1, 1859.

To all whom it may concern:

Be it known that I, O. V. JIrsoN, of

also, of the link (Z, is connected to the lever O, by an adjustable sleeve 6. The beam G,

On the upper ends of the Rochester, in the county of Monroe and has its fulcrum at f, at the upper part of a State of New York, have invented certain support 9, attached to the frame B, at one 5 new and useful Improvements in lVeighingside. The beam G, at one side of its ful- Scales; and I do hereby declare that the crum has a notched upper edge, as shown following is a full, clear, and exact descripat 71, in Figs. 1 and 3, and at each side of tion of the same, reference being had to the the beam G, there is a longitudinal ledge 2', annexed drawings, making a part of this just at the bases of the notches.

Fig. 3, is a plan or On the notched portion of the beam G, a top view of ditto. Fig. at, a transverse secmetal block H, is placed. In the upper 15 tion of a portion of ditto, taken in the line part of this block, two rollers is, Z, are placed. 3 y, Fig. l. The roller 7c, works over the notched sur Similar letters of reference indicate corface of the beam but the roller Z, has a responding parts in the several figures. grooved periphery and its edges bear on the This invention relates 1st, to a novel a ledges 2', 2', at the sides of the beam, as shown 20 plication of weights to the scale beam, as clearly in Fig. 4. In the lower part of the hereinafter fully shown and described, block H, a pinion m, is placed, said pinion whereby the weights may be adjusted or gearing into the rack g, and having a knob moved with facility, articles weighed in a 70 at each end of its axis. On the upper very exact manner, and the tare also weighed. part of the block H, a slide I, is placed. 25 The invention relates, 2nd, to an adjust- This slide has a pointer P, at each side, said able sleeve placed on the scale beam for the pointers projecting down over the sides of purpose of rendering the connection of the the block H, and above scales m stamped beam to the platform adjustable, to comor engraved at each side of the block. To pensate for the adjustment of the platform the block H, a clevis a, is attached.

This construction of the platform frame, whereblock is placed loosely on the beam, or the by the same may be readily increased or recess of the block through which the beam diminished in size, according to the desired passes is made sufiiciently large to allow the 35 i r ar a of the platform, .and the lever, block to be adjusted both vertically and lonalso, which is attached to said frame rengitudinally on the beam, said block being dered capable of being lengthened or shortsecured in the desired position by set screws ened, as may be required. 0.

The lever C, has two arms K, K, attached 45 C, is a lever which may be formed of a to it by links 2, 6, said links being suspended flat metal bar, one end of which is fitted in from an adjustable sleeve 21., on said lever. or passes through a socket D, of Tshape, The outer ends of the arms K, K, pass and which is suspended freely by links 6, through sockets I), r, in which they may be or in any other proper manner, from a secured at any desired point by set screws 50 curved support E, attached to the bed A. 10,10.

The lever C, is secured in the socket D, or L, L, are diagonal bars the inner ends of prevented from casually sliding therein, by which are fitted in the sockets a, v, and semeans of a set screw 0, shown in Figs. 2 cured therein by set screws (4 (4 The outer F and 3. The opposite end of the lever C, is ends of the bars L, L, are fitted in sockets 55 attached by a link (Z, to an adjustable sleeve 5 6 which are suspended by links 0 to links nuts (Z are placed, said nuts being above the frame B. and the links 0, at one end of the frame B, passing through T-shaped slots 6 in the frame, the slots 7, that receive the links at the opposite end of the frame B, being straight and having a transverse position relatively with the frame B. The platform rests on knife-edged bearings 9 The platform, being of ordinary construction, is not shown.

From the above description it will be seen that by turning the knobs 713 the block I-I, may be moved with facility, and the roller 70, made to fitin either notch 71., on the beam G, the roller Z, working or moving on smooth surfaces, 2', i. In light beams, and consequently small scales, the block H, may be moved directly by hand, but in large scales and corresponding-sized beams, the racks j, and pinion m, will prove a valuable aid. The block H, is of course, a weight, and the notches form a scale in which the roller is, fits and designates the weight of the article on the platform when the latter is counterpoised. The slide I, designates the fractional parts of the units of the beam Gr, the pointers Z, indicating the same on the scales -m. By means of the slide .9, on the graduated plate 1, the tare may be weighed, and by adjusting the block J, on the beam and the nut q, for the purpose of counterpoising and balancing the beam, the nut g, admitting of a very nice adjustment to obtain a perfect balance.

It will be seen that the lever C, may be so adjusted as to extend out from the device a greater or less distance, as desired, and it will also be seen that the bars K, K, L, L, admit of being adjusted longitudinally, as they are fitted loosely in their respective sockets u, d, 'v, 11, b b and the links 0 also allowed to be adjusted in the frame B. These bars, therefore, which form the frame of the platform may be expanded and contracted to suit dilferent sized platforms, and as the sleeve F, may be adjusted on the beam Gr, it follows as a matter of course that the beam and platform may be counterpoised at any adjustment of the platform frame, or lever G.

I do not claim separately any of the parts herein shown and described, but

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The sliding block H, when provided with the 1'0ll61s is, Z, and slide or supplemental weight I, arranged and combined as shown, for the purpose specified, and with or without the rack j, and pinion m.

2. The adjustable block J provided with the slide or weight .9, graduated bar 1", in combination with the nut or supplementary weight g, as and for the purpose set forth.

3. The attachment of the lever C, to the platform frame, as shown, whereby the same may be adjusted farther in or out from the frame, as circumstances may require.

a. The arrangement of the bars L, L, L, L, K, K, with their sockets o, '0, b b and with the frame B, substantially as shown; to admit of the adjustment of the bars to receive platforms of greater or less size, as required.

5. The employment or use of the sleeve F, attached or applied to the beam G, as and for the purpose specified.
